Neutral position adjustment device of flight control system and neutral position setting method thereof

Abstract

The invention belongs to the adjustment and control techniques of a flight control system and relates to a neutral position adjustment device of the flight control system. The neutral position adjustment device of the flight control system comprises a moving part at the transfer site of the system, a fixed base and a neutral pin, wherein the moving part and the fixed base are internally provided with neutral position holes with consistent sizes, and the neutral position holes are integrally connected through the neutral pin; and bushings are pressed in the neutral position holes of the moving part and the fixed base. The neutral position adjustment device of the flight control system simplifies the system adjustment process, decreases the repeated work, shortens the system adjustment period, and ensures the favorable neutrality of a linear system of the control system and the adjustment state of the system. Furthermore, the invention provides a neutral position setting method of the flight control system.

Description

technical field [0001] The invention relates to an adjustment control technology of an aircraft control system, and relates to a neutral position adjustment device and a neutral position setting method of the aircraft control system. Background technique [0002] The flight control system includes the elevator control system, aileron control system and rudder control system, which are used to control the aircraft to achieve pitch, roll and yaw. As an important functional system of an aircraft, the design of the flight control system is crucial, and it directly affects the flight safety of the aircraft. [0003] Generally, the manual control system of large and medium-sized aircraft has a relatively long line system, and the transmission relationship between the cockpit and the rudder surface is relatively complicated, and it needs to go through many intermediate conversion links, so the system adjustment is difficult. Due to the excessive system transmission parts will prod...

AI Technical Summary

Problems solved by technology

If the adjustment of a transmission link is not in place, more parts will be needed to compensate, sometimes even the design compensation margin is not enough, and the state of system adjustment is very unsatisfactory. At this time, many parts will appear out of tolerance (such as : Insufficient opening of the rudder surface, leaking tie rod threads, asymmetric left and right movement of parts, small system clearance, uneven system control force, etc.), which makes the final state of the system worse, affects the state of the entire system, and ultimately affects the performance of the aircraft. The state of the control system affects the control quality of the aircraft, so the adjustment of the final state of the control system of the aircraft is very important

[0004] Due to the shortcomings of complex system adjustment, long cycle, large amount of rework, difficult guarantee of system status, and poor consistency or similarity of the system adjustment status of each rack, it has caused a lot of troubles in design and production. The aircraft control system lacks an effective adjustment method. Generally, it is manually adjusted step by step, which requires a lot of repeated work, a large workload, and a long adjustment period.
